Description
Technical field
The utility model relates to a kind of emission-control equipment, belongs to gas purification dedusting technology field.
Background technology
Gas purification dedusting is a new technical barrier, the flue dust of a large amount of coal tar and cotton-shaped viscosity is contained in raw gas, and raw gas temperature is higher, generally reach 400-500 DEG C, raw gas is inflammable and explosive, should not adopt conventional method for dust removal, also contains BSO and BaP in raw gas simultaneously, contaminate environment, is detrimental to health.Conventional treatment process is: introduced in sealed furnace fly-ash separator by pipeline by raw gas and carry out dedusting, but this method exists shortcoming, and one is that dust-collecting bag cannot resistant to elevated temperatures problem, and work-ing life is limited, and replacement cost is higher; In addition owing to only using bag-type dust, in raw gas, macrobead flue dust is comparatively large to cloth bag abrasive action, easily causes cloth bag to damage, causes efficiency of dust collection to decline.
Utility model content
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of emission-control equipment, raw gas is lowered the temperature, tornado dust collector pre-treatment, pass through air cooling again, then entering the dedusting of sealed furnace fly-ash separator, is a kind of novel, simple and convenient, efficient gas cleaning dust-removal system.
The utility model technical solution problem adopts following technical scheme: by cleaning shaft, telescopic joint, flue water cooling tube, tornado dust collector, connecting tube, air-cooler, pipe connecting, sealed furnace fly-ash separator, gas exit pipeline, fly-ash separator bottom discharge valve, bottom discharge valve, soot cleaning system is formed; Arrange one section of flue water cooling tube, tornado dust collector, an air-cooler before described sealed furnace fly-ash separator respectively, raw gas is entered successively by pipeline; Described flue water cooling tube front end arranges telescopic joint; Described air-cooler outlet is connected with sealed furnace dust collector ash hopper inlet mouth; Described sealed furnace house outlet is connected with booster fan.Telescopic joint is added in pipeline one end of conveying high temperature raw gas, the impact preventing pipeline from being expanded with heat and contract with cold under different operating mode and damaging, flue water cooling tube is installed after telescopic joint, raw gas declines in temperature after flue water cooling tube, enter again in tornado dust collector, by the effect such as inertial impaction, natural subsidence removing macrobead flue dust, be then cooled to further within 200 DEG C through air-cooler, then enter the dedusting of sealed furnace dust-collecting bag.Described pipeline water cooling tube adopts jacket structured, and pipe diameter size is identical with transport pipe, passes through Flange joint.Tornado dust collector and air-cooler are connected by cleaning shaft, and air-cooler is connected by cleaning shaft with sealed furnace fly-ash separator.Described sealed furnace fly-ash separator top is provided with nitrogen injection deashing device.Be provided with ash bucket in the bottom of described tornado dust collector and sealed furnace fly-ash separator and be located at the unloading valve of ash bucket bottom.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model is transformed traditional sealed furnace fly-ash separator; namely on cleaning shaft, increase telescopic joint can effectively prevent pipeline from damaging because expanding with heat and contract with cold; flue water cooling tube first through newly increasing before raw gas enters sealed furnace fly-ash separator, by cooling high-temperature fume, protection cloth bag.Raw gas can effectively remove macrobead flue dust through tornado dust collector, reduces dust greatly to the abrasion of cloth bag.Lowered the temperature further by air-cooler, raw gas temperature can be down to less than 200 DEG C, making up existing dust-collecting bag cannot resistant to elevated temperatures problem, increases the service life, and reduces production cost, improves safety coefficient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As Fig. 1, a kind of emission-control equipment, by cleaning shaft 1, telescopic joint 2, flue water cooling tube 3, tornado dust collector 4, connecting tube 5, air-cooler 6, pipe connecting 7, sealed furnace fly-ash separator 8, gas exit pipeline 9, fly-ash separator bottom discharge valve 10, bottom discharge valve 11, soot cleaning system 12 is formed; Described sealed furnace fly-ash separator 8 arranges one section of flue water cooling tube, 3, tornado dust collector, 4, air-cooler 6 above respectively, and raw gas is entered successively by pipeline; Described flue water cooling tube 3 front end arranges telescopic joint 2; Described air-cooler 6 outlet is connected with sealed furnace fly-ash separator 8 ash bucket inlet mouth; Described sealed furnace fly-ash separator 8 outlet is connected with booster fan.During work, by cleaning shaft 1, raw gas is delivered to dust removal installation, cleaning shaft 1 is provided with telescopic joint 2, flue gas enters flue water cooling tube 3 and cools, enter tornado dust collector 4 again and remove most of flue dust, enter air-cooler 6 again by connecting tube, raw gas enters sealed furnace fly-ash separator 8 from air-cooler 6 bottom by pipe connecting, is exported after bag-type dust by gas exit pipeline 9 again.
Composition graphs 1, raw gas has very high temperature, raw gas is allowed can effectively to reduce its temperature through flue water cooling tube 3, tornado dust collector bottom is provided with discharge valve 11, in raw gas, a large amount of dust settles down after tornado dust collector 4, its underpart can be accumulated in, can regular deashing by discharge valve 11, raw gas is after air-cooler 6 further cooling, the working condition requirement of sealed furnace fly-ash separator 8 can be reached, after the operation of for some time, the dust of dust collector ash hopper inner accumulated can be got rid of by bottom discharge valve 10.Dust on cloth bag can increase systemic resistance, often runs for some time, can carry out jetting deashing by nitrogen soot cleaning system 12, reduces the dust on cloth bag.The utility model effectively can solve existing dust-collecting bag cannot resistant to elevated temperatures problem, extends cloth bag work-ing life, reduces production cost, improve safety coefficient.
